Stealth Technology


960911-F-00000-001 The Department of Defense announced today, Sept. 11, 1996, the deployment of U.S. Air Force F-117A Nighthawk aircraft, shown in this file photograph, to the Persian Gulf area of operations. The F-117A Nighthawk is the world’s first operational aircraft designed to exploit low-observable stealth technology. The F-117A can employ a variety of weapons and is equipped with sophisticated navigation and attack systems integrated into a state-of-the-art digital avionics suite that increases mission effectiveness and reduces pilot workload. Detailed planning for missions into highly defended target areas is accomplished by an automated mission planning system developed, specifically, to take advantage of the unique capabilities of the F-117A. The aircraft will be deploying from the 49th Fighter Wing, Holloman Air Force Base, N.M. DoD photo.

To understand how stealth technology works you first must know how radar works. Radar is a system that shots radio waves then waits for the radio waves to bounce back. Based off how long it takes for the radio waves to bounce back, is determine by how far the object is. From that information, all stealth technology needs to do is prevent the radar from picking up the single to that bounced off the vehicle.

There are way to do this, but I will only write about two. The first one is to deflect the single away from the receiver. This can be done by angling panels on the plane to so the single bounces not towards the receiver. The second way is to absorb the single. This is done by having special small iron partial to convert the radio waves to thermal waves which radar can’t pick up.

This is important to engineering because it allows our aircraft to get closer to the enemy before the enemy notices. That can help keep the war away from home keep use safe.
